Does anyone know of a (preferably free) screencapture program for Mac OS X that is similar to ImageGrab
, in that it lets you take multiple caps of a movie and specify how often the caps are taken (such as every 3 frames)? I'm looking to make a mini-movie type icon, but I can't find any program that reliably takes screencaps often enough so that the animation looks smooth in the icon. The program would also have to be able to handle AVIs, since that's what I would be capping from.
Or, if that's impossible, does anyone know of a program for Mac OS X that can convert AVIs to GIFs? (In a comment to a post somewhere in the memories, which I can't find now, someone referenced a program—not by name, sadly—that they have that can do that, but I suspect it's only for Windows.)
Thanks in advance!
ETA: I forgot to mention that I've tried VLC, and it doesn't do automatic multiple captures, so you have to rely on your ability to hit the hotkey over and over again, which gives you a cap every half second, if you're good. I've also tried InstantShot!, if that means anything to anyone, and Googled around for that last hour or so without any luck.
